Hi oc I'm laughing because you are asking me for my thoughts instead of
going to Google. I think that is a very smart move on your part. You now not only want QM foam,but "virtual" foam.(give me a break will ya) I will work on that however. Lets just stay with your champagne bubbles,and my beer foam. We are taking the same thing "bubbles" I remember this guy Glaser(sounds a little like my last name well he invented the bubble chamber. oc we can't see elementary particles,but these elementary particles going through liquid hydrogen causes the hydrogen to boil along their tracts. This leaves a wake of bubbles that can be observed and measured.. I can't remember if I posted my thoughts on "sonoluminescence" in this group. In a liquid very tiny bubbles are not squeezed by the fluid,but collapse like an implosion of a supernova. This implosion is created by sound waves. Here is the most interesting part this bubble reaches a temp. of 185,000 F that is hotter than the sun's surface. That is a lot of compression to get that hot(yes) Now comes more interesting stuff it now has to expand,and this expansion could be as fast as "c",but Einstien need not turn over in his jar for a second would be about a million times to long for this action. These are some of the dynamic features of foam. Let me add Glaser was drinking beer and that is how he came up with the bubble chamber. When I put whipped cream on my Mexican sweet potato pie I'm eating foam I shaved this morning with foam. The waves washing along the shoreline turn to foam. Nature uses foam in the sub-micro realm,and man uses it everyday in his macro world. Bert It was Moby that reminded me about the waves. |

Yeah Bert, i 'member that rap about sonoluminescence. Here's a website
on it- www.sonoluminescence.com/ Sonoluminescing bubbles make a great analogy of the quantum foam and 'sea of particles'. There has to be that energetic *underlying medium* to drive the bubbles into forming. String theory imputes such a vibratory underpinning to space. But since the 'no medium' mandate is in place, this presents quite a conundrum reconciling the 'Something that is yet Nothing.' So they gotta invent some curled-up "extra dimensions" embedded in the 'Nothing'. oc |

Sorry. It's just that in the news reports of Fomalont's measurements they
kept citing that Earth would not know of the sun's sudden absence for 8 minutes - this conjured up a mental picture of a "wave front of gravity" continuously emanating from the sun. I found info on gravity waves at: http://www.physicscentral.com/action/action-02-8.html . Of course now I seek clarity as to what you guys think Formalont was trying to detect if it wasn't "gravity waves" being affected by Jupiter's gravity. "Bill Sheppard" wrote in message ... From Aunt Buffy: OK...here is my summary of conclusions: 1. The jury is still out on the speed of gravity and/or speed of gravity propogation/waves. 2. Thus the question of whether gravity and "gravity waves" are the same thing is mute until point 1 is resolved. Even under the void-space model, the distinction between gravity and "gravitational waves" should be perfectly clear (even for Jb). 'Thought experiment'- suppose you have a massive body like a neutron star sitting alone in space, not accreting anything, just sitting there quietly. Is it radiating 'gravitational waves'? Obviously not. Pretty soon another neutron star comes wandering by and gets captured, and now you have a co-orbiting pair, which *is* radiating GWs, as appears to be the case in the Hulse-Taylor pulsar, for instance. If Jb still thinks gravity and GWs are the same thing, then he's dumber than a box of rocks. oc |

Fomalant was trying to measure the 'speed of gravity', which has nothing to do with 'gravitational waves', Buffy. Just as electromagnetic(EM) radiation arises from oscillating charges. GW radiation arises from oscillating masses (or co-orbiting masses like binary neutron stars or binary black holes, or from massive events like a supernova going off or a BH collapse). Try a Google under 'binary black hole merger' and 'black hole ringdown' for some real insight into GW generation. You'll probably find some audio simulations of GW signatures. Clearly, Fomalant's experimant on the 'speed of gravity' did not in any way involve 'gravitational waves'. Try a Google on 'LiGO' and 'LISA'. These are projects designed specifically to look for GWs. GWs have not yet been *directly* detected, but circumstantial evidence for them has been. Google for 'Hulse-Taylor Pulsar'. oc |

However, the model has the same problem as all non-relativistic solutions; and entrainment gives some particular problems of its own, like why we don't see the postions of stars move as their light passes through the zone of 'entrainment' ahead of Jupiter or the Moon - there should be refraction as the light slows down and speeds up again through this zone. Quite reasonably, Bill asks how QM and GR can be accommodated in the same model; however he believes that the FSM is the only model that provides an integration of both and can't be persuaded that it is a flawed model in itself. |

From OG:
The old coot asks how QM and GR can be accommodated in the same model; however he believes that the FSM is the only model that provides an integration of both and can't be persuaded that it is a flawed model in itself. Well then old chap, the onus is now on you to demonstrate a better model.. of _literal causation_ , not downstream descriptions of effects. ..entrainment gives some particular problems of its own, like why we don't see the postions of stars move as their light passes through the zone of 'entrainment' ahead of Jupiter or the Moon - there should be refraction as the light slows down and speeds up again through this zone. The refractiom or bending _was_ demonstrated by Eddington in the 1919 solar eclipse. How much refraction do you expect so see around low-mass objects like Jupiter or the moon? Much less, how much differential do you expect to see 'ahead' vs. 'behind'? In the split second it takes for a ray of light to pass by say, Jupiter, how far does the planet translate laterally? You're being a little silly really. ..(at one point he thought that the effect of the charge on an electron would be less than that of a proton 'because the electron has less mass'); so any attempt to discuss basics comes to naught. Egg on face for sure with that one. Score one for OGster. Hubba hubba. But again you're demonstrating your penchant to dwell in details and particulars while _hiding from_ the overview, 'big picture' that deals in EXPLANATIONS OF CAUSATION rather than downstream descriptions of effects. Certainly one can recite effects till he's blue in the face, but it has no relevance to causation. So if you can demonstrate a better model, then put it up. The floor is yours___________ . oc |
